不同土地利用/覆被类型对水质的影响——以安徽省滁州市琅琊山风景区为例

Effects of Different Land Use/Cover Types on Water Quality——Taking Langya Mountain Scenic Area in Chuzhou of Anhui Province as an Example

为了解不同土地利用/覆被类型对水质的影响,以安徽省滁州市琅琊山为研究对象,分析土地利用类型与水质指标之间的相关关系。对2016年7月采集的水样进行水质状况分析,选用的指标有PH、电导率、矿化度、盐度。结果:(1)琅琊山水质与土地利用类型显著相关,耕地、建设用地与水质参数呈负相关,林草地与水质参数呈正相关;(2)建立优选多元回归模型,pH、电导率、矿化度、盐度与各土地利用类型之间的相关系数R值分别为0.653、0.856、0.901、0.859。结果表明各土地利用类型对水质因子影响显著。

In order to further understand the effects of different land use/cover types on water quality,the paper analyzed the correlation between land use types and water quality indicators at Langya Mountain. The paper tested PH,conductivity,salinity and salinity of water samples collected in July 2016. The results showed that：（ 1） Water quality of Langya mountain was negatively correlated with type of land use,farmland and construction land,instead positively correlated with the forest grass land.（ 2） The correlation coefficient R values between PH,conductivity,salinity,salinity and various land use types were 0. 653,0. 856,0. 901,0. 653 in multiple regression model. Various land use types had significant influence on water quality factor.
